Abstract

The invention discloses an FPGA (Field Programmable Gate Array)-based single event effect test system for a NAND FLASH device and belongs to the technical field of space radiation effect and reinforcement technology. The system comprises a communication interface module, a peripheral control platform, an upper computer, a tested device, an analog source, a power switch and an FPGA, wherein the FPGA comprises a cache module, a control module, an input/ output reading and writing module, a sensor input/ output module and a detection result module. The system can be used for testing the single event effect of a large-capacity NAND FLASH device to obtain single event effect characteristic parameters, and further the anti-single event effect capability of the tested device can be estimated through the analysis on the obtained parameters.

Description

technical field [0001] The invention relates to an FPGA-based NAND FLASH device single event effect test system, belonging to the field of space radiation effect and reinforcement technology. Background technique [0002] Because NAND Flash memory has the advantages of low power consumption, good chip pin compatibility, no loss of data after power failure, and no need to re-refresh data in a short period of time, etc., it has been used in space in recent years. However, charged particles in the space radiation environment can easily induce single event effects in NAND Flash devices, which will have a certain impact on the on-orbit performance of satellite payloads. At the same time, with the requirements of long life and high reliability of satellites, the evaluation of ground single event effect test of devices is particularly important. Since the structure of NAND Flash devices above 1G is different from other static memory structures in the past and is more complicated, ...
